I these are what you are looking for. believe<a target=_blank class=ftalternatingbarlinklarge href="http://www.smiths-medical.com/catalog/bronchial-hygiene/palm-cups/palm-cups-percussors.html">http://www.smiths-medical.com/...m-cups-percussors.html</a>
I could not find where you can get them though. We got ours from the CF clinic many many years ago.
You can find the contact info for this company and ask them where you can get this product. I figure at least, you now have the exact name for this product.
Good luck. I'll keep looking to see if I can find anything else out.
Well dog gone it, if I'd just waited a minute... Did a search for palm cup percussors and found a few sites that sell them. Looks like they have to ordered by the box and run about $165. This may/should be covered by your insurance. Found a place where you can purchase a single pair instead of the whole box of 40-50!

Be sure to look for the correct size. I wouldn't think you would actually need an entire box, it'd last a lifetime that's for sure.
Hope I've helped.
